What is the number of contour lines you would need to show a change om elevation of 1000 feet on a map with a contour interval of 200 feet?
Ok so each line is equal to 200 feet. So let's pretend you're starting at 0 how many lines would you need to get to 1,000? Line 1 =200 then Line 2=400 then line 3=600 then line 4=800 and finally line 5=1,000
_____1,000 feet
/
_____800feet
/
_____600feet
/
_____400feet
/
_____200feet
/
So how many lines did it take?

What does 0 represent on a topographic map?
The number 0 on a topographic map usually represents the contour line for sea level, also known as mean sea level. This line shows where the elevation of the land is equal to the water level of the ocean.
How can one calculate the flood recurrence interval?
To calculate the flood recurrence interval, you can use the formula T (N1) / M, where T is the recurrence interval, N is the number of years of record, and M is the rank of the flood event. This formula helps estimate how often a flood of a certain magnitude is likely to occur based on historical data.
Which is a higher elevation 40 feet below sea level or 14 feet below sea level?
40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.
What does not change when an ion forms?
The number of protons and neutrons does not change when an ion forms.
Relief is the number of microbes in soil?
This is not accurate. Relief refers to the differences in elevation within a landscape or terrain. The number of microbes in soil is related to soil health and fertility, which is influenced by various factors including moisture, temperature, and organic matter content.
What is the contour interval if ten contour lines show a change in elevation of 2000 feet?
The contour interval would be 200 feet. This is calculated by dividing the total change in elevation by the number of contour lines.
What is the number of contour lines that you would need to show a change in elevation of 1000 feet on a map with a contour interval of 200 feet?
To show a change in elevation of 1000 feet on a map with a contour interval of 200 feet, you would need 5 contour lines. This is calculated by dividing the total change in elevation (1000 feet) by the contour interval (200 feet), resulting in 1000 ÷ 200 = 5. Each contour line represents an elevation increase of 200 feet, so five lines would represent the full 1000 feet change.
What is the formula to work out a contour interval of a map?
The formula to calculate the contour interval of a map is the difference in elevation between two contour lines divided by the number of contour lines crossed. This provides the elevation change between each contour line on the map.
What are the factors effecting contour intervals?
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
How on a topographic map how would you show a island in the ocean with an elevation of 80 feet if the contour interval is 10 feet?
You would just add 10 every contour line you pass until you get to the number 80.
What is the contour interval for a topographic map of the volcano?
The contour interval for a topographic map of a volcano typically ranges from 10 to 100 meters, depending on the size and slope of the volcano. This interval is used to represent changes in elevation and help visualize the terrain features of the volcano accurately.
What is the difference in elevation between two neighboring contour lines?
This depends entirely on how close they are, and what number they have written on them. Sometimes they can be minimal distances apart, in which case they're liable to be quite a substancial gap between the 2 lines, in comparison to them being 4 centimetres apart on the map, in which case it would be a very minimal rise/decline.
What is the elevation of hachure line A?
Well, darling, the elevation of hachure line A is simply the height above sea level at that particular point on the map. So, grab your magnifying glass and check the legend for the contour interval, then count the number of intervals from sea level to hachure line A. Voilà, you've got your elevation!
How does a relief of an area determine the contour interval used on a map?
Roxanne Lipsey: Contour lines are drawn at specific intervals, such as every 10 feet, 20 feet or 30 feet. Each line represents a multiple of the scale chosen. Using the 10-foot scale as an example, each contour interval would represent a 10 feet change in elevation.
On a topographic map how would you show an island in the ocean with an elevation of 80 feet if the contour interval is 10 feet?
You would just add 10 every contour line you pass until you get to the number 80.
What is the elevation between one contour line and the next one on a map?
It depends completely on the type of map and the scale of the map. Look several contour lines above and below the area of interest. Often, the elevation is printed on every 5th contour line. Divide the difference by the number of spaces between the two lines. Example, one contour line says "1000" and the next one with an elevation says "1500". If there are 4 lines in between these two, it is 100 ft per contour line. In some areas, you will need to follow a contour line around the map to track down the elevation of that line. Easier still, check the legend on the side or bottom of the map. The example showing the colors or symbols used may also tell the contour interval if it is consistent for the entire map.
What is a index contour?
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
